I am wondering if locking the job quantity and date could lead to any potential issues. We have been seeing an increasing amount of change suggestions and it takes a lot of time to process them.
We find locking jobs similar to locking POs. It is beneficial in reducing suggestions. However, you will get new job suggestion or new PO suggestion where demand is not being met (date and quantity wise) by existing jobs / POs. New suggestions are one row to look at rather than the many rows (with negatives too frequently), on change suggestions, and we find it can make analysis in timephase inquiry easier.
One thing that may be missed when locking (ie., suppressing change suggestions) - If say a customer changes their sales order and reduces it down… no suggestion to cancel or reduce. Also, if a job requires less for some reason… no suggestion to cancel or reduce.
Therefore, we only use the lock checkboxes where we are certain to not desire ANY date or quantity change to the job or PO.

Thanks Nancy ! One thing we are find is the change suggestions on jobs that are in process. There is nothing we can do on those.
For companies that have a short mfg duration:
1: leave unfirm until it NEEDS firmed
2: firm a day or 2 before work will start (or if you have purchase-direct materials)
3: just before first operation starts or first material issued, RELEASE the job.
4: simple BPM fires when job is released, BPM locks qty and schedule because it is now unchangable.
